广东省信宜市钱排银岩—东田金银多金属矿远景区找矿前景
|
摘要
银岩—东田金银多金属矿远景区土壤金元素异常明显,矿点普遍。通过对典型矿床成矿地质背景、矿床地质特征进行研究,分析成矿地质条件,认为矿床金银矿床(点)受岩性及构造控制,NW北向含金脆-韧剪切带是主要的控矿和贮矿构造,并且延深大的特点可指导其他矿点找矿。破碎带蚀变岩型金银矿找矿远景较大,是进一步找矿的重要类型。提出有望预测区。
There are many ore occurrences in Yinyan-Dongtian gold-silver polymetallic perspective area in Xinyi city of Guangdong Province.The gold element soil anomaly is also obvious.Based on the study of metallogenic geological background and geological characteristics of typical deposits,and the discussion of metallogenic geological conditions,it is considered that the gold and silver deposits(ore occurrences)are controlled by lithology and structure.The NW gold-bearing brittleness ductile shear zone is the main ore-controlling and ore-hosted structure.Moreover,the extension characteristics of large depth can be referred to guide the prospecting of other occurrences.The Au-Ag deposits of altered rock and fractured zone type is an important ore type for further exploration with a great prospecting potential.The expected forecast area is pointed out in this paper as well.
